To all whom t may concern Be it known that 1*,.lPERLEY lt. GLASS, a citizen Yof the United States, vresiding at Brookline, in the county of Norfolk and State of Massachusetts, have invented certain improve-ments in Eyeleting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to improvements in machines for inserting fasteners. While it is herein shown as embodied in a machine for inserting eyelets in the uppers of boots and shoes it will lbe understood that many of its featuresI are not limited in their appll cation to this or any other particu-lar form of machine.

lt is importantwfor purposes of speed and precision that the eyelet to be set should be positioned for delivery by the racewa'y accurately in alinement with the eyelet setting device and that when presented for delivery the eyelet should be so held that the setting device may engage and draw it from the raceway without retardation or displacement which would in any Wjay subject the setting device to strain. This is'particularl true in machines embodying an expansib e setting member such, for example, as that shown in Letters Patent of the United States No. 1,271,720, granted Jul 9, 1918, upon the application of H. W. ilenwaiy, for in such a machine if the upsettin dieencounters the eyelet flange instea of passing freely through the eyelet barrel a section of the upsetting die is liable to be broken.

With a view to improving the operation of fastener inserting machines an important feature of the invention consists-in means for positively positioning the endmcst fastener in the race-way preliminarily to its delivery to the setting device. As herein shown in an eyeleting machine this result is secured by providing a spindle which assumes positlve control of the second 4eyelet of the series while said eyelet is in the raceway and during the cycle ofthe machine next prior to the delivery of the first eyelet, the spindle being arranged to enter and hold the second eyelet while the eyelet and raceway are relatively moved to feed the eyelet raceway. Such construction permits the use of a spindle sui'licientlystrong and best shaped for the function of positionin the eyelet without reference tol other limiting considerations and effects such positive treatment of the eyelet as toy insure uniform results. 4

Another feature 'of the invention consists in a ra'ceway provided at its end with a movable jaw or latch for holding and p0- sitioning the endmost fastener and so constructed and arranged that it may be moved to release the endmost eyelet and leave'it free at the time of its delivery. An advantage of such a construction is that after .an eyelet or other fastener has been moved to the point of delivery to the setting device it is re eased lso that no strain whatever is imparted to the setting device in the delivery operation. As herein shown the retaining latch is so positioned and shaped that the 'movement of another eyelet in the raceway serves to disengage the latch from the endmost eyelet, in this'case such other eyelet being positively moved by the positioning spindle above discussed.

A difliculty heretofore encountered in eyeleting machines has been that, by reasonof long use and wear or faulty adjustmenhthe movable racevvays have at times developed a side play which has permitted inaccuracy" in locating the eyelet to be delivered to the inserting die. 4 Vith a view to obviating t defect, another feature of the invention consists in a raceway supported upon links haiT` ing a vpositive guidin connection with the machine frameat a point adjacent to the .end of the raceway. In the illustrated embodiment of the invention the raceway is provided with a rojecting tongue arranged to slide in a guideway formed in the machine frame beneath the raceway and adjacent to its delivery end. By such` construction the v path of movement of the raceway is accurately-and positively controlled and thel possibility of side play eliminated.

It sometimes happens that y'the barrel of an eyelet is more or lessobstructed 'by a iin of enamel or a chi of eyelet metal which has not been entirey removed in manufacturing theeyelet. This is detrimental to rapid and accurate handling of the eyelet for obvious reasons and in accordance with another feature of the invention it is proposed to clear the eyelet of any such obstruction before it i's presented 'to the setting devices.

` ing the eyelet in the raceway but it is within the scope of the invention. to rovide separate or different means for per orming this operation if so desired.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which- Figure 1 is a View in perspective of so much of an eyeleting machine as is necessary to understand the present invention;

Figs. 2 and 3 are detail views in perspective' Figs. 4, 5, 6 and 7 are views in side elevation illustrating the successive steps in the cycle of the machine;

Fig. 8 is a sectional view through the lower setting device;

. Fig. 9Nis a sectional view on an enlarged scale showing the setting devices in position lat the conclusion cf the setting operation, and

Fig. 10 is a plan view of the end of the raceway.

The machine frame 2 is provided with 'vertical bearings for a plunger 4 carrying the setting devices. The plunger 4 1s reciprocated vertically by a cam track cut in the rear face of the cam disk 54 upon the shaft 52. The frame also supports a stationary work plate 70 above which operate a punch lever 8 0 ,and a feeding lever 34 which will be referred to hereinafter.

The lower setting die 10 is shaped at its upper end to fit the flange of the eyelet to be set and is adjustably mounted in the upper end of the plunger 4, being shouldered to rest upon a hollow bolt 6 threaded into the plunger and provided with a lock nut 8. The setting die l0 is'bored to receive the upsetting die member, the setting surface of which is formed by the lower surface of an overhanging shoulder made up of expansible sections 12. The body of the upsetting die 14 is hollow to receive the stern of thev dieeexpanding member 24 and at its lower end is threaded into a movable angle piece 16. The angle piece 16 is guided for movement in the machine frame and projects in through a slot 5 in the wall of the plunger as shown in Fig. 8. Beneath the overhanging end of the angle piece 16 is disposed a hollow flanged core 18 between which and the bottom of the plunger 4 is interposed a stiff compression spring 2O tending at all times to elevate the angle piece 16 and the upsetting die 12 carried thereby. The stem 26 of the die-expanding member 24 is provided at its lower end with a head 28 against which bears the upper end of a compression and tending to elevate the die-expanding member. It will be understood that the eyelet to be set is delivered to the setting die 10 and the clenching operation is effected by relative movement of the die l() and the upsetting die 12 during which the spring 20 is compressed. The novel features of this form of expanding set and the associated parts have not been claimed herein since they form the subject-matter of a co-pending application of Ralph F. Knight, Serial No. 179,243, filed July 7, 1917.

Eyelets are supplied to the setting die 10 in line with the member 12 by a raceway 72 supported in part by a link 71 and pivots of which one is indicated at 7 3 in Fig. 1. The aXes 0f these pivots are at right angles to a vertical plane extending from front to rear as is customary in machines of this type. The raceway is provided upon its lower side with a downwardy projecting tongue 7 4 which projects into a groove 75 formed in a vportion of the machine frame 2 and so disposed as to guide the raceway accurately Without side play in its path toward and away fromlthesetting die 10. rli`he means for moving the raceway are not herein shown as they form no part of the present invention but may be of any desired construction.

The raceway is provided at a point above or remote from its delivery end with a spring stop 77 which servesto retain in the raceway a line of eyelets terminating short of its delivery end. A retaining member 76 provided with a recess for positioning the eyelet to be delivered is pivotally mounted upon the raceway and normally pressed into eyelet engaging position by a spring piny 78. rThe retaining member76 is also provided with a projection 79 disposed oppositely to lthe end of the yielding stop 77 and so de released and left free to be engaged by the sectional spindle of the upsetting die 12.

The machine frame 2 is provided with a vertical guideway parallel to and at the rear of the plunger 4 in which is mounted a reciprocatory slide 42 carrying at its upper end a spindle 40 so located and shaped as to enter the barrel of that eyelet which is held in the' raceway by the yielding stop 77. The slide 42 and its spindle are operated by a cam 50 formed on the periphery of the cam disk 54 through an arm 44 which engages a slotted stud on the slide 42 at its inner end and is. fast at its outer end to a shaft 46 journaled in a bracket 60 secured to the machine frame. At its frontend the shaft 46 is provided with a cam arm 48 having a roller to run upon the cam surface 50 and a spring which maintains engagement acompa with the cam. The cam 50 is so shaped that the spindle 40 is elevated when the raceway is moved forwardly to delivering position and is maintained in such position until the raceway has been retracted to its rearmost position and the operation performed on the preceding eyelet.

It will be noted thatl the spindle 40 is solid in construction and of such diameter as nearly to fill the barrel of the eyelet, being rounded at its upper end so as to center the eyelet in entering its barrel and suiiiciently strong in construction to punch out'and remove from the barrel any obstruction which may be caused from enamel ora chipof eyelet metal within the eyelet barrel.

rlhe punch lever 80 above referred to is provided with a punch 82 which coperates with a punching die 84 arranged beneath the punch in a slot in the work plate 70. rlChe punching operation is effected by the downward movement of the punch 82 which is effected by swinging the lever 8O by a cam not herein shown. The lever 34 carries a feeding member 32 which includes a yielding pin 30 cupped at its lower end for engagement with the die-expanding mem-- ber 24, as shownin Fig.9. The punching operation takes place at one side of the setting position whereupon the punch 80 is retracted from the work and moved to an inoperative position. The feed lever 34 is subsequently moved so as to carry the feeding pin 30 into alinement with the previously punched hole, then depressed to engage the vvork and finally moved toward the left to bring the punched hole into alinement with the setting devices.v V

rll`he setting devices vand eyelet positioning spindle are shownin their initial position in Fig. 4, the en-dmost eyelet in the raceway 72 having been drawn forward into the recess in the retaining member 76, as shown in Fig. 10, and the spindle 40 occupying its'lower position. When the machine is started the punching and feeding operations 'take place as above outlined and the plunger 4 is lowered while the raceway 72 is advanced to bring the endmost eyelet into line with the sectional spindle of the upsetting die 12. rlhe plunger 4 and the spindle 40 are then elevated as shown in Fig. 5, the upsetting die passing through the endmost eyelet and the spindle 40 passing into. the barrel of the eyelet held by the yielding stop 77. The raceway irs then retracted as shown in Fig.

` (S. the eyelet engaged by the spindle 40 being held stationary and forced against the projection 7 9 of the retaining member 76 thereby swinging the retaining member outwardly and freeing the endmost eyelet. rThe spindle -r40 4is then held at rest while the plunger 4 continues its upward movement to effect the clenching operation, as shown in Fig. 6. rl`he position of the parts at the moment of clenching the eyelet is shown in Fig. 7. L The plunger 4 and the'spindle 40 are then both lowered to their initial positions and the eyelet which has reviously 'been engaged by the spindle 40 .is eft in the raceway engaged and positioned by the retaining member 7 6.

As herein shown through the lining part of the upper only as is customary in setting invisible eyelets and consequently the upward movement of the eyelet is inserted the upsetting die member 12 is terminated by a stop 62 on the bracket 60 when it has passed through the lining part 90 of the upper as shown in Fig. 9. rlthe feeding pin 30 is engaged by the die-expanding. member 24 and forced upwardly out of the work but is then arrested in its movement so that in the continued elevation of the plunger 4 the sectional upsetting die `12 isk forced upon the conical :surface of the member 24 and the die then expanded into upsetting condition. Duringthis operation both the spring 20 and the spring 30 are compressed and as soon as the-feeding lever is elevated the dieeXpanding member is returned to its initial position and the upsetting die permitted to contract so that it may be drawn downwardly through the barrel of the clenched eyelet. i
